Panel Display Error Types and Solutions
E021: The power voltage is too low
1) The battery may need to be charged.
2) Replace with a battery that has a larger discharge power.
E022: The power supply voltage is too high
The power supply voltage is too high, check the battery output voltage.
E023: The power supply voltage is abnormal
The power supply voltage is abnormal, check the current battery voltage.
E031: The Glow Plug wire is open-circuit
1) Check if the glow plug's connection wire is disconnected.
2) Check if the glow plug's connection port is loose.
3) Give the glow plug's positive and negative wires a brief charge to test if the spark plug is heating up.
E032: The Glow Plug is short-circuited
The Glow plug is damaged, or the mainboard is faulty.
E041: The oil pump wire is open circuit
1) Check if the connection wires of the oil pump are disconnected.
2) Check if the connection wires of the oil pump are loose.
E042: The oil pump is short-circuited
Check if the oil pump is blocked or not working.
E05: High temperature alarm (Casing temperature >230°C)
1) Check if the cold air intake is blocked.
2) Check if the hot air outlet pipe is bent.
3) Check if the fan is working properly.
4) Add gasket to the temperature sensor.
E061: The motor wire is open circuit
Connect the positive and negative terminals of the battery to the motor interface and check whether the motor is rotating.
E062: The motor is short-circuited
The motor is damaged, or the mainboard is faulty.
E063: The Glow Plug wire is open-circuit
1) Check if the impeller is stuck.
2) The gap between the magnet on the wind wheel and the Hall sensor on the controller is too large.
E07: The communication between the mainboard and the control screen is abnormal
1) Check if the connection port of the control screen is loose.
2) Check if the connection line (blue) of the control screen is open circuit.
E08: The flame is extinguished
1) Check whether there is a lack of oil, oil low-temperature solidification, oil road blockage, oil pipe collapse, too many gas pockets in the oil pipe, or oil pump stuck.
2) Check if the air intake and exhaust duct are unobstructed.
3) Check if the casing temperature sensor is fully in contact with the casing and if the pressure spring is strong.
E091: The Glow Plug wire is open circuit
1). Check if the wiring of the temperature sensor is disconnected.
2). Check if the connection port of the temperature sensor is loose.
E092: The motor is short-circuited
The temperature sensor is damaged, or the mainboard is faulty.
E10: Unable to start, ignition failure
Unidentifiable comprehensive reasons. Please take videos and pictures, a thorough inspection of the spark plugs. oil pump, combustion chamber, air duct, motor, and fan. circuit may be needed.
Conclusion
By understanding the error codes on your TB2 diesel heater, you can quickly diagnose and fix common issues. Regular maintenance and timely troubleshooting help keep the heater running smoothly. If problems persist, check connections, fuel flow, and key components—or document the issue for further assistance.
